hi guys,
I'm trying to finish my wind smulation project but I'm having problems.
What I'm doing is creating a for loop to display from
0 seconds to 3600 seconds or 1 hour of wind simulation
My first Column displays the Time, and the second column displays the wind result which is a calculation from three inputs.
cin >> Avg_Wind;
cin >> High_Gust;
cin >> Low_Gust;
Upper_Limit = Avg_Windi + High_Gust;
Lower_Limit = Low_Gust;
Avg_Wind = rand_float (Upper_Limit, Lower_Limit);
What I need to do is make some kind of calculation that would increased by 10 the Avg_Wind for a period of 300 seconds.
I created a function on the botton but for some reason it doesn't increased by 10 for a period of 300 seconds and but adds 10 to the wind result for the whole hour
Please give me a hand if you have more questions let me know and I will try to explain better .
Thanks Here's what I have so far
